摘要：
Design considerations of terahertz quantum well photodetectors are presented. Quantum well parameters are determined by the condition of having the first excited state in resonance with the top of the barrier. Due to the small transition energy many body effects need to be included to accurately predict the spectral response peak position. A trade-off in doping density between absorption strength and operating temperature needs to be made. Predictions are compared with experiments and future directions are pointed out.
